I want to create an iPhone and Android application for an existing website that is write in PHP and has a MySQL database. The application will need to use as much of the existing website and/or database as possible to show a subset of the most popular items from the website for purchase via the websites shopping cart. A nice to have would be social networking in the app for Facebook and Twitter. Detailed information will be given to the top 5 companies who have the expertise and experience demonstrated to do this work and once they sign a NDA.
